Very interesting. And he does look quite unique for a pastel enchi. When you breed him, I suggest pairing him with at least 1 normal female who's genetics are 100% known and at least one codon female who doesn't carry any of the males genes (i.e. enchi and pastel) and who's genetics are also 100% known, so that in at least 2 clutches you are 100% certain from which parent the genes came from, especially if something weird pops up. This is why normals and single gene females are still important .
My picks of mates for him would be a Normal, a fire, an enchi and a yellowbelly.
